molly is bird - watching at the coast. she has seen 2 egrets and 4 other birds. considering this data, how many of the next 39 birds molly sees would you expect to be egrets? egrets
Answer
Explanation:
Step1: Calcular la proporción de egrets
La proporción de egrets en los pájaros ya vistos es $\frac{2}{2 + 4}=\frac{2}{6}=\frac{1}{3}$.
Step2: Calcular el número esperado de egrets
Multiplicamos la proporción por el número de pájaros futuros. $\frac{1}{3}\times39 = 13$.
Answer:
13
